Growing mushrooms alongside trees could provide a nutritious food source for millions of people while mitigating the effects of Climate change, according to a recent study by scientists at the University of Stirling. The research highlights the potential of cultivating edible ectomycorrhizal fungi (EMF) in forests to sequester carbon, reduce the need for deforestation, and incentivize tree planting.

Professor Paul Thomas and Professor Alistair Jump, who authored the study, found that EMF cultivation could sequester up to 12.8 metric tons of carbon per hectare annually and produce a nutritious food source for almost 19 million people per year. They suggest that this system could help mitigate climate change by actively reducing greenhouse gas emissions, which is not the case for other major food groups.
The cultivation of mushrooms alongside trees also has significant benefits for biodiversity and Conservation, as it helps reduce land-use conflict between forestry and food production, reducing the need for deforestation to make way for crops. Moreover, it can trigger rural socio-economic development and incentivize increased tree planting rates.
The authors of the study believe that this food production system is scalable, realistic, and could have a powerful impact on reducing greenhouse gas emissions. They call on researchers to join the field and for Support from relevant agencies to realize these benefits.
Professor Thomas said, “This is a huge benefit which means that by producing this food we can actively help mitigate Climate change. When we compared this to other major food groups, this is the only one that would result in such benefits—all other major food categories lead to a greenhouse gas emission during production.”
According to the study, if the EMF cultivation system had been implemented in the forestry activities that took place during the last ten years in China, it could have produced enough food to feed 4.6 million people annually. The authors suggest that if this system was combined with current forest activities, the food production levels could be enormous, potentially feeding millions of people and mitigating the effects of Climate change.
The study suggests that the cultivation of mushrooms alongside trees is a promising solution to mitigate the effects of Climate change while providing a valuable food source for millions of people. However, more research is necessary to develop the technology further, and the Support of relevant agencies is critical to realizing its potential. We can all contribute by supporting sustainable forest practices and reducing food waste to help mitigate Climate change and ensure food security for all.
